Antique brass US NAVY ship bell Sea Hawk large original

I bought a couple of items from a local estate recently the man was retired military. The largest items were this brass ship bell and a brass steering wheel from a submarine I have been told. This antique bell is just about the best I have seen for sale. It is mounted on a newer hardwood plaque and is in very good condition. This bell is large, it is 10 3/4 inches tall from the top of the nut to the bottom rim. The opening is 12 inches across. This is marked U. S. Navy on the mounting arm. Date I am not sure. T is a tag on the plaque that reads USS SEA HAWK, I do not know if this came off that ship or what the connection might be. This bell is heavy and will ship for $30.00
